3D printed Vibration Rock Tumbler with magnetic drive

Welcome to my TH-cam video about the 3D printed Vibration Rock Tumbler! The 3D printed rock tumbler took about 4-5 months to develop. The goal was to polish rocks to an impressive shine, which takes some time. During the development phase, various challenges arose, in particular problems with spring breakage. Fortunately, these problems were successfully resolved and the Rock Tumbler has been working perfectly for several months now.
The Rock Tumbler is controlled via an Arduino. By using two potentiometers, the on and off time of the magnet can be precisely controlled. This enables precise adjustment of the frequency and amplitude of the vibrations. A spring system with compression and tension springs makes it possible to adjust the preload of the tumbler and thus the stroke very precisely. This is one of the main advantages of my 3D-printed DIY tumbler, as the machine can be perfectly adapted to individual needs. From coarse to very fine vibrations, everything is possible with this device.

Wow very very cool!❤ what a rewarding machine, hats off again sir

Have you considered adding a drop of manual dish-washing fluid? It may help lubricating the tumbling rocks, and facilitate cleaning of the bowls afterwards. You may want to compare concentrated fluid with non-concentrated; the former may make way too much foam.

[@FraensEngineering]

Yes, I have used dishwashing liquid. However, it foams a lot. That's why I switched to water with washing powder.

[@TeslaSpain]

Wow man ! This is a good project

[@MoFTB]

Perfekt 👌

[@AngryArmadillo]

Very cool build. How long do you let it run for?

[@FraensEngineering]

I used 5 sanding and polishing stages with silicon carbide. K80, K220, K500, K800 and finally aluminum oxide. The K80 ran for about 3 weeks. The others a lot shorter. In total, it must have been about 1.5-2 months.

How's the wear on the plastic containers?

[@FraensEngineering]

The black SLA container was printed with Tough Resin. I mainly used this one. I haven't noticed much wear yet. The orange FDM printed container is made of PLA. It started to leak after 2-3 weeks. I haven't been able to test the transparent one yet as I only used it for the final polishing step.

Cool! Does the vibration bring rocks to a better level of shine than a tumbler can? Or take less time?

[@FraensEngineering]

Unfortunately I can't say whether it makes a better shine due to the lack of a rotary tumbler. However, it works a little faster due to the many vibrations. If you ask around among the professionals, vibration tumblers are very popular for the polishing steps. I therefore assume that the shine will be better.

@@FraensEngineering Cool! Didn't know that, I'd only seen the cheap tumbling ones.

@@FraensEngineering - Did you see some of the comparison videos while you were working on this?
This one seems quite useful.

Yes, I know that video.

@@FraensEngineering - Where would your design be in comparison to those four examples, in terms of cost and efficiency?

[@christopherd.winnan8701]

Please can you include details of time required to tumble to given stones and how much power the unit requires to function. Can you make it work on a solar panel for example?
Also, how does the build price compare to the larger industrial versions?

[@FraensEngineering]

Hi, I have not measured the power. However, I estimate between 10-20W. The solenoid draws ~0.5A at 24V. Theoretically it could work with enough sunlight and battery.

[@Quadikorn]

How much would one of these cost to get printed/where would I go to get someone to print this for me?

[@FraensEngineering]

Hello, unfortunately I can't print out the parts for you. However, there are very good online providers who can do this. I had the container printed here: jlc3dp.com/?from=Fraens
